To be fair, LFR Archimonde was quite difficulty pre-nerf and so is Socrethar (as the Construct doesn't have all of its abilities unlike normal+ raid).
Honestly, I believe that in LFR, the players are trained too much on DPS the boss to worry about any other mechanics. That and lower DPS in general.

Ah didn't see that lobbying action. Well best of luck on removing determination, I think your chances are slim... unfortunately, I do believe the devs intention is for LFR to be a place where people win just by wiping enough times. There's a reason why it's called "tourist mode".
